I was FOLLOWING about 20 to 25 people/entities on Twitter, but in the past 24 hours no matter how many times I repopulate my FOLLOWING list, it empties within minutes.
I don't see this listed as a bug by anyone else via a Google search.
I only see MY tweets and I am able to tweet normally.....and there are views showing up on my tweets.

My Twitter account is used solely to Tweet illegally parked city buses and harassment by city bus drivers(in a residential neighborhood).
Could a local business or city government have filed a complaint, limiting my Twitter account?
I got the usual "form letter" reply when asking Twitter for help.

Possible, but unlikely IMHO. Probably Twitter has given you one of its various SELECTIVE bugs — I mean, bugs that affect only some users.
Selective bugs happen on Facebook as well.

For the time being you might replace your following list with temporary bookmarks on your browser.
I don't have a smartphone and I have no idea of how the Twitter "app" works
